3 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION i
RELATED TO AMENDMENT NO. 161TO FACILITY OPERATING LICENSE NO. DPR-49 1
I IOWA ELECTRIC LIGHT AND POWER COMPANY CENTRAL IOWA POWER COOPERATIVE CORN BELT POWER COOPERATIVE DUANE ARN0LD ENERGY CENTER DOCKET NO. 50-331
1.0 INTRODUCTION
By application cated April 14, 1989, Iowa Electric Light and Power Company, et al., (the licensee), proposed an amendment to the Duane Arnold Energy Center (DAEC) Facility Operating License No. DPR-49 to extend the DAEC Integrated Plan (the Plan) 2 years beyond the current expiration date of May 3, 1989. The proposed amendment does not change the. Plan itself. The Plan requires that the licensee follow the schedule of the DAEC plant modifications mandated or proposed by NRC, or identified by the licensee.
The proposed amendment does not involve changes to plant systems, components, or Technical Specifications.
The Integrated Plan was originally approved in Amendment No. 91, dated May 3, 1983.
The objective of the Integrated Plan is to integrate all planned DAEC plant hardware and operations modification schedules over a period of 5 years to assure that individual tasks are performed in an efficient and cost / resource-effective manner.
2.0 EVALUATION On May 3, 1983, the Commission approved Amendment No. 91 to the DAEC operating license incorporating a license condition which requires the licensee to follow its plan for integrated scheduling of hardware and operations-related modifications for the DAEC (the Plan). The license condition was extended by Amendment Nos.-125 (July 9, 1985) and 148 (November 25,1987).
The approved Plan identifies two categories of modification schedules.
Schedule A identifies modification schedules established by the prevailing Rules and Orders. Schedule B consists of modification schedules of:
(1) regulatory items identified by the NRC which woulo result in plant modifications, procedure revisions, or changes to staffing requirements; B908170081 890eos PDR ADOCK 05000331 J
P PNU
i (2) items' perceived by the licensee as potential NRC requirements; and l
1 (3) all major DAEC tasks resulting from mandates of agencies other than the NRC, or the tasks identified by the licensee.
The Plan has been in existence for a period of 6 years. The licensee submits semiannual reports which cover proposed activity for the next 5 years. The staff's review of the original Plan approved in Amendment No. 91 and the updates in the semiannual reports for the period between November 3, 1987 and May 3,1989 indicates that only one of the items in Schedule A was delayed.
This delay was due to DAEC awaiting NRC guidance on the station blackout rule.
In Schedule 8 for the same period, only seven items were delayed. Of the seven items delayed in Schedule B, only two are regulatory items identified by NRC which have implementation dates committed to by the licensee. The other five items were initiated by the licensee. The delays of the two regulatory items identified by NRC have been for a good cause. Therefore, the staff finds that the Plan has been helpful in maintaining firm centrol on DAEC modification schedules. The Plan has also contributed to the Commission's continued awareness of the projected activities of the licensee over a period of 5 years. This knowledge has f acilitated negotiations with the licensee on any differences in the NRC and the licensee positions related to realistic scheduling of NRC-mandated modifications. Because the Plan is the same as was previously approved anc provides for systematic and orderly implementation of modifications which are intended to enhance plant safety, and the experience with the Plan has been good, the staff finds that the extension of the Plan for an additional 2 years will continue to promote safe operation of the plar.t. The staff concludes that the extension of the Plan is acceptable.
3.0 ENVIRONMENTAL CONSIDERATION
S This amendment relates to changes in recordkeeping, reporting, or administrative procedures or requirements. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(10).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the anendment.
4.0 CONCLUSION
The staff has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
